RECOMMENDED ENCLOSURES
Please note that these enclosure volume recommendations are for the internal airspace inside the enclosure
and include the displacement of the subwoofer and ports. When choosing your enclosure type, please pay
close attention to your specific woofer, failing to use the correct enclosure may result in lower power handling
and poor sound quality.
To calculate the internal airspace required, take the internal dimensions
of the box. First multiple these number by themselves and then divide this sum by 1728. (W x H
x D) / 1728.
Please contact your authorized PowerBass dealer for other designs and specifications.
(Even though these
subwoofers can be used in a ported enclosure, PowerBass recommends a sealed enclosure for
optimum performance and sound quality.)
